I’m trying to get a Python 3 program to do some manipulations with a text file filled with information. However, when trying to read the file I get the following error:


Traceback (most recent call last):  
  File "SCRIPT LOCATION", line NUMBER, in <module>  
    text = file.read()
  File "C:\Python31\lib\encodings\cp1252.py", line 23, in decode  
    return codecs.charmap_decode(input,self.errors,decoding_table)[0]
UnicodeDecodeError: 'charmap' codec can't decode byte 0x90 in position 2907500: character maps to `<undefined>`
